Castlewood State Park

Park Information

In the early 1900s, the area that’s now Castlewood State Park was a popular retreat for partying St. Louisans. The dance clubs are gone, but the winding Meramec River and the lush valley that surrounds it remain. The park has hiking and mountain biking trails that range from those great for first-time riders to ones that even the most experienced will return to time after time. The park is considered one of the best mountain biking locations in the St. Louis area. Good fishing, broad meadows filled with wildlife, and plenty of recreational facilities make the park a favorite for people who want an adventure or just to get away.
